The story is set in a divided city named Eridana, split between the Tseberun Dragon Empire and the Lapetodes Seven Cities Alliance by the Orielal River. In this world, individuals known as spell formulists use spell formulas—chemical reactions enhanced by specialized weapons called Magic Staffs—to combat dangerous creatures like Dragons, Aions, and Enormes, which also employ these formulas. The narrative centers on Gaius Sorel and Gigina Ashley-Bufh, the sole workers at the Spell Formulist dispatch office Ashley-Bufh & Sorel Co. They handle various client requests that require the application of spell formulas.
